+Subject: [PATCH] lxc: containter: fix build with glibc 2.36
+
+With glibc 2.36, sys/mount.h and linux/mount.h conflict:
+https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
+
+lxc_container.c imports sys/mount.h and linux/fs.h, which pulls in
+linux/mount.h.
+
+linux/fs.h isn't required here though. glibc sys/mount.h has had
+MS_MOVE since 2.12 in 2010
